What Dust Collector is Right For My Application?

Reliable dust collectors are critical for the optimal operation of most industrial and manufacturing facilities. A well-chosen dust collector will ensure high air quality for both workers and equipment. Without an appropriate filter, particles can clog up your equipment, contaminate products, reduce overall operational efficiency, and put worker health at risk.

Dust collectors are available in three standard designs: baghouse, cartridge, and bin vent collectors. To determine the best design for your needs, it is important to consider every aspect of dust collection in your facility, including:

  • Type of dust
  • Expected dust volume
  • Size restrictions for the collector
  • Emissions requirements
  • Temperature of the surrounding environment

3 Main Types of Dust Collectors

The three most common dust collector designs are baghouses, cartridges, and bin vents. Each type of collector exhibits different characteristics that make it particularly useful for specific applications.

Baghouse Dust Collectors

Baghouse dust collectors are the most widely used dust collector style. They tend to be larger than other types of dust collectors and are well-suited to high-volume and high-temperature applications. Baghouse systems employ fabric bags to capture dust particles in gas or air moving through the system. Contaminated air is pulled through the filters, the filter catches the dust, and clean air is expelled.

Cartridge Dust Collector Systems

Cartridge collector systems are similar to baghouse dust collectors but use a cartridge filter made of pleated filter media instead of fabric bags. The filters may be composed of specialized medias including spun-bond, water-resistant, and oil-resistant materials, depending on the needs of the application. They are housed in a sealed chamber, where dirty air is pulled through the cartridges, trapping the dust and allowing clean air to be expelled.

The pleated surface of these filters allows for improved filtration over baghouse systems, as more surface area is available and finer filtering materials can be used. This makes cartridge dust collectors particularly useful for the filtration of fine particles and fumes. Cartridge dust collectors are typically more compact than baghouse collectors, and can be installed in confined spaces where a large collector is not suitable.

Bin Vent Dust Collectors

Bin vent dust collectors are typically installed on top of silos and other large containers to vent displaced air during loading. Dust and debris flow naturally upward as material is propelled into the container using a pneumatic or compressed air system. The bin vent dust collector prevents dusting and loss of product during loading by filtering the displaced air as it flows out of the container and keeping an airtight seal.

Advantages of Dust Collectors

Depending on the needs of your application, each type of dust collector offers unique benefits.

  • Baghouse collectors. Baghouse collectors offer large scale filtration of large- to moderate-sized particles, ideal for use in manufacturing and industrial settings where a great deal of material must be filtered on a regular basis.
  • Cartridge dust collectors are ideal for applications that require the filtration of smaller particles on a reduced scale. The pleated filters and versatile materials of cartridge filters allow them to be easily adapted to meet the needs of specific applications. In addition, they are smaller than their baghouse counterparts for easy installation in more confined spaces.
  • Bin vent dust collectors see particular use on bins and containers which require the filtration of air expelled from the top of the container while it is filled. Fans are not always required but may be added to assist the movement of air.

Dust Collector Applications

Dust collectors are used in an extensive range of industries, depending on the particular needs of the application.

  • Baghouse filters are used in high-volume, high-temperature applications such as lumber milling, automotive manufacturing, mining applications, and foundries.
  • Cartridge filters, on the other hand, are more useful for applications with fine particles and fumes, such as welding, laser cutting, wood processing, agricultural feed production, and fiberglass processing.
  • Bin vent filters are specialized and highly valuable for silos, storage containers and other high-dust and material holding applications.

    It’s interesting that baghouse dust collectors do well with high-volume applications. My uncle needs to replace his dust collection system and is thinking about installing a baghouse dust collector since he has a big factory. I’ll have to share this with him as he continues to search for a good one for his factory.
